Abstract

A novel palladium-catalyzed cascade allylic amination/intramolecular hydroamination/isomerization process of protected enynol 1 and primary amine 2 has been explored, which constructs the important 1,2,5-trisubstituted pyrroles. This transformation offers an alternative synthetic methodology capable of generating substituted pyrroles in a straightforward way.
